Subnanosecond Electro-optic Modulation of Triggered Single Photons from a Quantum Dot

Abstract:

Control of single photon wave-packets is an important resource for developing hybrid quantum systems which are composed of different physical systems interacting via photons. Here we extend this control to triggered photons emitted by a quantum dot, temporally shaping single photon wave-packets on timescales fast compared to their radiative decay by electro-optic modulation. In particular, telecommunications-band single photons resulting from the recombination of an exciton in a quantum dot with exponentially decaying wave-packets are synchronously modulated to create Gaussian-shaped single photon wave-packets. We explore other pulse-shapes and investigate the feasibility of this technique for increasing the indistinguishability of quantum dot generated single photons.
